当前海水养殖废水的排放量已超过陆源污水,是导致海洋环境不断恶化的重要原因之一.为了保护海洋环境,减少疾病传播,海水集约化养殖废水经处理后方能排放入海已成为海水养殖业发展的必然趋势.由于海水盐度效应和海水养殖废水污染结构的特殊性,增加了养殖废水的处理难度,研究海水养殖废水处理技术十分必要.文章综述了国内外海水养殖废水生物处理技术研究现状和存在的问题,认为应该加强在工艺选择、处理能力与效能以及微生物等方面的研究.
Nowadays the amount of marine aquaculture wastewater has surpassed the amount of sewage.Marine aquaculture wastewater may have negative impacts when released into the environment without being treated.Their impact on the environment depends on the total amount or concentration released and the assimilative capacity of the environment for the particular constituent.The treatment of marine wastewater is very difficult because of their high saline concentration and unique contaminant composition.In this paper,the biological treatment methods used in intensive aquaculture systems were introduced and drawbacks were pointed out.The study in technological selection,treatment efficiency and microorganisms of marine wastewater treatment should be strengthened.
